recommendations! Published in 2017 at "Engineering Structures"

DOI: 10.1016/j.engstruct.2018.01.065

Abstract: Abstract The high amount of confining lateral steel required by seismic design provisions for rectangular bridge columns can cause steel congestion which may hinder the placement of conventional concrete (CC). Self-consolidating concrete (SCC) eliminates or… read more here.
